Blow Molding
Blow molding process is a manufacturing process through which plastics are formed. The process entails pumping in air to inflate soft plastic in a mold cavity, resulting in the formation of hollow-thin walled plastics. Blow molding is an innovative manufacturing process that has made tremendous contributions to a sustainable economy. The essence of the process is seen in various sectors of the economy such as the packaging of medicine in the health sector, and packaging of drinks in the beverage sector.Since these plastics and containers usage is in large volumes.
Blow Molding History
The initial idea of blowing hot materials with hot air was actualized by Syrians in the first century BC. Egyptians later revolutionized the approach to blow molding in 1700-1600 B.C. Among the verified individuals who first launched the process were William Kopitke and Enoch Ferngren. Blow molding process typically originated from glass blowing. This profound idea was set in motion when Hartford Empire Company bought a blow molding machine in 1938, and that marked the onset of commercial blow molding. However during the 1940’s custom blow molding product variety was at its minimal and it was not until later on, that the production rates and wide range of variety increased. As new inventions actualized, they brought technologies and technical mechanisms essential in producing hollow bodied pieces. The technologies facilitated plastics manufacturing which is replacing glass in some situations. Plastic bottles mass production took place in America in 1939. Later the blow molding technology was adopted by Germany which has now surpassed all other manufacturers making it a renowned blow molding machine manufacturer.
